AH and HH Bolts

[Buggles]

Hi Everyone,

A newbie question: my KTM repair manual mentions HH bolts and AH bolts, and each have a different torque for tightening them.

Which is which? I think AH is an Allen Head bolt, but is that correct? And what is an HH Bolt?

I've tried doing a picture search on Google, but all it comes back with is rifles

All help much appreciated!

only guessing with an engineering background.
ah i would guess is allen head
hh i would guess hex head (standard bolt spanner type)
